The Goodman® brand DSZC18 16 to18 SEER Heat Pump uses the chlorine-free refrigerant R-410A and features energy efficiencies and operating sound levels that are among the best in the heating and cooling industry. The DSZC18 contains the two stage, high efficiency Copeland® UltraTech scroll compressor, which provides improved temperature and humidity control. This unit is designed for the consumer who desires superb comfort and quiet operation.

All Goodman 16 to18 SEER heat pumps must be installed with a bi-flow thermostatic expansion valve. This valve is installed in front of the indoor evaporator coil inline with the line set piping.

This heat pump requires an indoor air handler or evaporator coil as part of a complete system. What tonnage coil or air handler should you use? It depends on two factors about the outside portion of the heat pump system: 1) the tonnage, and 2) the efficiency rating (listed as "SEER"). Usually, high efficiency heat pumps are required to use a larger tonnage evaporator coil than the tonnage of the outside heat pump. (For example, a 2 ton heat pump might be paired with a 3 ton or 3.5 ton evaporator coil.) To find the specific coils or air handlers that are recommended by Goodman for this heat pump, please click on the Accessories tab above. (Also, you can view Goodman's specifications sheets at the Documents tab above).

In order to achieve the 18 SEER efficiency this heat pump must be installed with the manufacturer recommended evaporator coil, a Goodman variable speed furnace, variable speed air handler, or variable speed modular blower and thermostatic expansion valve (TXV). (See the Accessories tab above for most compatible products, or Goodman's spec sheet found under the Documents tab above to verify heat pump efficiency with particular equipment combinations.) An 18 SEER system will reduce your electric bill approximately 12% - 14% more than a 16 SEER system.

If you are installing a heat pump with a backup heat source which will be a fuel furnace, you will need to install an electronic all fuel kit. This kit switches between the two heat sources as needed and prevents both the heat pump and backup heat from running at the same time. Alternatively, you can install the Honeywell VisionPro 8000 (TH8320U1008) thermostat which has the all-fuel kit functionality built into it already, in which case an external all fuel kit would not be needed.

Please note that this heat pump comes pre-charged with R-410A liquid refrigerant and by Federal law cannot be released to the atmosphere. You can purchase this equipment without being EPA certified, and if you are mechanically inclined you may perform about 90% of the equipment installation yourself. However we strongly recommend to have a professional heating/cooling contractor do the final part of the installation including managing the refrigerant. An HVAC contractor has the tools and know-how to do this work. Also, having a contractor perform the final startup and inspection of this heat pump validates your warranty with Alpine.

SEER

Seasonal Energy Efficiency Ratio (SEER) is a measure of cooling over an entire season. It is determined by comparing the amount of cooling produced in BTUs in relation to the amount of electricity used. A higher SEER means a system is more energy efficient and would provide comfort at a lower utility cost than a lower SEER system.

Refrigerant

Inside air conditioning systems are liquid/gas refrigerant. There are two types of this refrigerant available for use, R-22 (more commonly known as Freon), and a newer alternative R-410A.

An air conditioning system does not consume refrigerant, but reuses it. As long as there are no leaks in the refrigerant circuit, there is no need to ever add more refrigerant to an air conditioning system.

Although R-22 is an effective refrigerant, if it is released into the atmosphere it can contribute to the depletion of the Earth’s ozone layer. The EPA has mandated the phasing out the use of R-22. It is being replaced by R-410A.

As of 2010, manufacturers are required to make all new air conditioners with R-410A. However, R-22 is still available for sale in existing pre-2010-manufactured equipment, and for use in servicing existing R-22 equipment. By 2020, R-22 will no longer be manufactured, but will still be recycled and available for sale.

Compressor Type

Reciprocating compressors use a piston to compress the refrigerant.

Rotary compressors utilize a roller rotating eccentrically inside a cylinder and a spring mounted blade always rubbing against the roller. As the eccentric rotates towards the blade, the space is decreased and the refrigerant is compressed. Rotary compressors are very efficient.

Scroll compressors consists of 2 scrolls to pressurize refrigerant. Often 1 scroll is fixed and the other orbits eccentrically compressing the gas between the scrolls. Scroll compressors are quiet, smooth and offer highest efficiency ratio of all compressor types.

Scroll Ultratech™ compressors are advanced scroll compressors which offer more features and better diagnostics.
